sent into the filter and discharged through the goose-neck, as indicated by the arrow, in a purified condition for drinking.

Referring to this filtering-tube, I would have it understood that the compound of which it may be composed forms no part of this invention, as any filtering compound known to the art and capable of successful use may be used in connection with the mechanical features of this myinvention. The art also furnishes the ideaof a tubularfiltering device, such form of filter or purifier I understand to be in abroad and general sense well known at this date. I further claim it only in connection with my flexible coupler Whenthe same is adapted to connect therewith substantially in the manner-and upon the principles herein set forth, whatever be the compound or ingredients that enter into the structure of the tube.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, with a case, a cap therefor, and a filter proper having a projecting shoulder at one end and mounted within said case, of a flexible coupling between said filter proper and said cap and consisting of an annular recessed portion embracing said shouldered end of the filter proper and-of a tubular portion opposite thereto, the said cap having an extension matching said tubular portion of the coupling, and a stud-bolt supporting said coupling and mounted in said cap extension.

2. In a liquid-purifying device, the combination, with a casing, a cap therefor, and a filter proper mounted within said casing, of couplings between said cap and casing and said cap and filter proper, respectively, the first consisting of an annular portion or ridge extending outward to be gripped between the edges of the cap and the casing and of flaring portions thinned at their edges and pressing against the inside of the casing, the other consisting of an undercut recessed portion forming a lip adapted to support the filter proper, and an oppositely-extending tubular portion adapted to embrace a matching portion of the cap and be pressed tightly against the same by the pressure of the water, and means to maintain the said couplings and their adjacent parts respectively in engagement.

In testimony whereof I affix my signature in presence of two witnesses.

FRANK K. WAY.
